Final answer:
The autocratic team decision-making structure discourages criticism and debate as it involves top-down decision making with little to no input from group members.
Step-by-step explanation:
The team decision-making structure that explicitly discourages criticism and debate is autocratic. An autocratic decision-making style involves a leadership pattern that flows from the top down where decisions are made unilaterally by the leader with little to no input from group members. This structure differs from other decision-making structures like democratic, which encourages group participation and consensus building, and laissez-faire, which is a more hands-off approach allowing group members to self-manage. In contrast to the autocratic style, consultative decision-making does involve seeking input, although the final decision rests with the leader.
